Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A900 is significantly lighter (278g ) than the Pentax XG-1 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Nikon Coolpix A900 nor Pentax XG-1 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Nikon A900 and Pentax XG-1's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Nikon A900 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Pentax XG-1 has a fixed type screen which provides less flexibility in shooting positions compared to A900.
